IMPROVEMENT IN FIRE-POT LININGS FOR COOK-STOVES.

Specification forming part of Letters Patent No. 204,155, dated May 28,1878 yapplioation filed May 8, 1878.

To all whom it may concern:

Be it known that I, RUFUS J. KING, of Dayton, in the county ofMontgomery and State of Ohio, have invented certain new and usefulImprovements in Fire Pot Linings for (look-Stoves; and I do herebydeclare the following to be a full, clear, and exact description of thesame.

This invention is an improvement in that class of cook-stoves in whichthe fire-pot is lined with corrugated cast-iron instead of firebrick, mypurpose being to provide such a back lining as will resist thedestructive action of the heat for a much longer time than is ordinary,for experience shows that the central part of the back lining is firstwarped and burned out. The novelty lies in forming in this back lining aconcavity facing the firepot, and in placing in this concavity verticalribs, whose edges are flush with the front face of the lining, so as tostrengthen the same.

In the drawing, Figure 1 is a front elevation of this lining. Fig. 2 isa sectional view of the same through the line as a; of Fig, 1.

A is a corrugated cast-iron lining-plate, differing from the ordinaryplate in having a central portion, B, concave longitudinally, and equalin length to about one-half of the whole plate. This concavity faces thefire-pot, and is subdivided by a number of vertical ribs, 0, whose frontedges, as seen in Fig. 2, are flush with the front face of the plate.These ribs are cast integral with the plate, and should be near enoughtogether to prevent the fuel from coming in contact with the back partof the plate. As seen, they are thicker in the rear than in front, andwhile I have shown them flush with the front of the plate, still theymight either project beyond it or not quite come up to it within theconcavity.

By thus making the lining concave and ap plying the ribs the plate isrendered much stronger against warping, without materially increasingits weight or the quantity of metal used.

The ribs would first have to be destroyed before the fuel could come incontact with the concave portion of the plate, and so the length of timerequired'to burn it out is increased.

I am aware that it is not new to construct a lining-plate with a centralconcavity covered bya removable and reversible plate, as exhibited inthe patent to J. Ziegler, November 27, 1876, No. 179,249; also, that itis not new to provide a fiat back plate with horizontal ribs to receivethe ashes, and thus protect the plate.

I claim as follows:

The herein-described fire-pot lining, consisting of the plate A, with acentral concavity, B, facing the pot, in which are located the verticalribs 0, with their front edges fiush with the front edges of the plate,substantially as set forth.

Witness my hand this 30th day of April, A.
